> The order of itemStateChanged events is different for RI and for our implementation. It isn't a bug because the behavior is unspecified, but some applications may rely on this issue
> import java.awt.event.ItemEvent;
> import java.awt.event.ItemListener;
> import javax.swing.AbstractButton;
> import javax.swing.ButtonGroup;
> import javax.swing.JRadioButton;
> public class Test {
>     public static void main(String[] args) {
>         ButtonGroup group = new ButtonGroup();
>         JRadioButton b1 = new JRadioButton("First");
>         JRadioButton b2 = new JRadioButton("Second");
>         group.add(b1);
>         group.add(b2);
>         b1.setSelected(true);

> Output:
> RI:
> First state changed
> Second state changed
> Second state changed
> First state changed
> First state changed

> Second state changed
